Objective: To observe the influence of electroacupuncture on depression and defects of neurological functions in the patients with post-stroke depression. Methods: 90 cases of the apoplectic patients confirmed clinically by CT or MRI were selected and divided randomly into three groups by digital table, 30 cases in each group. All three groups of the patients were treated for wind stroke, with electric stimulation added for the acupuncture group,Fluoxetine added for medication group, and placebo added for control group, continuously for 60 d. Results: Compared to the control group, the scores in Hamilton Depression Rating Scale (HAMD) and Modified Edinburgh-Scandinavia Stroke Scale (MESSS) decreased in the electroacupuncture group and medication group, and the scores in Barthel index increased (P＜0.05). The general therapeutic effects were better in the electroacupuncture group and medication group than in the control group, and the general therapeutic effects were similar in the electroacupuncture group and medication group. Conclusion: Eiectroacupuncture can improve depressive behavior and promote rehabilitation of the nervous functions.

Objective To investigate the clinicopathological significance of the expression of annexin A2 (ANXA2) in liver fibrosis and hepatocellular carcinoma (HCC).Methods The expression level of ANXA2 in normal liver,liver cirrhosis and HCC were examined by Western blot.The correlation between ANXA2 expression and clinicopathological parameters in liver fibrosis and HCC were analyzed by immunohistochemistry.Results Compared with the normal liver tissue,ANXA2 protein expression level increased significantly in HCC and liver cirrhosis,with the highest expression in HCC (P =0.000).There was significantly positive relationship between ANXA2 protein expression and stages for liver fibrosis (P ＜ 0.01).The expression of ANXA2 protein in HCC was closely associated with HBV infection,differentiation degree and the recurrence (P ＜ 0.05).In some cases,ANXA2-positive cancer cells were often dispersed in the periphery of cancer nodules and were adjacent to stromal cells.Conclusion Overexpression of ANXA2 may be involved in liver fibrosis and play a role in the development of HCC,indicating ANXA2 may serve as a diagnostic biomarker for liver fibrosis and tumor differentiation in HCC.

This study was aimed to compare the function of dendritic cells (DCs) in patients of Y in-Huang syn-drome and Y ang-Huang syndrome from the peripheral blood of HBV related hepatic failure. Jaundice patients of HBV related hepatic failure were divided into two groups, which were the Y ang-Huang syndrome group and Y in-Huang syndrome group. And a healthy control group was also established. The DCs were separated and cultured in vitro from PBMCs in the peripheral blood. Surface molecules such as HLA-DR, CD80, CD86, CD83 and CD1αwere detected by the flow cytometry. And the level of IFN- α and IL-4 in the supernatant of DCs were also de-tected. The expression difference of inflammatory cytokines and immune cells between Y in-Huang and Y ang-Huang syndrome in patients of HBV related hepatic failure were compared. The results showed that compared with healthy people, the expression rate of DCs phenotype such as HLA-DR, CD1α, CD83, CD80, CD86 in patients of HBV related hepatic failure was significantly decreased (P < 0.01); the excreted factor IFN-α had a significant rising (P < 0.01). Compared to Y ang-Huang syndrome group, the expression rate of CD83 and CD86 in the Y in-Huang syndrome group of HBV related hepatic failure patients was significantly reduced (P < 0.01). And the ex-creted factor of IL-4 had a significant rising in Y in-Huang syndrome group (P < 0.01). Compared to the Y in-Huang syndrome group, the excreted factor IFN-α in the Yang-Huang syndrome group had a significant rising (P< 0.01). It was concluded that DCs function of patients with HBV related hepatic failure in both Y in-Huang syn-drome and Y ang-Huang syndrome group showed low immune function. And the immune function of the Y in-Huang syndrome group was lower. There was excessive releasing of inflammatory factors in the Y ang-Huang syn-drome group. And there was enhanced anti-inflammatory cytokine expression in the Y in-Huang group.

Objective To determine the prognostic value of fight ventricular end-diastollc diameter (RVDD)in patients with chronic heart failure(CHF).Methods The clinical data of the in-hospital patients diagnosed as CHF were analyzed retrospectively.Telephone follow-up was carried out for all participants.The patients were divided into the survival group and death groups according to their clinical outcomes.The relationship between RVDD and death was evaluated by independent t-test and multivariate Logistic regression analysis.Results 1552 in-hospital patients were enrolled into the study.The mean age was 64.62 ± 10.45 years old,with 879(56.64％)male.After 3 years' follow-up,439(28.29％)patients died.Comparison of baseline data showed that gender,age,SBP,NYHA classification,the serum level of creatinine,LVEF,LVDD and RVDD were significantly different between the two groups(P ＜ 0.01);Multivariable logistic analysis showed that RVDD(OR=1.11,95％ CI:1.07-1.14,P ＜0.01),age(OR =1.03,95％ CI:1.02-1.05,P ＜0.01),creatinine(OR =1.02,95 ％ CI:1.01-1.04,P ＜ 0.01),LVEF(OR =0.93,95 ％ CI:0.92-0.97,P ＜ 0.01),LVDD(OR =1.13,95％ CI:1.09-1.17,P ＜0.01)and NYHA classification(OR =1.17,95％ CI:1.12-1.24,P ＜ 0.01)were independent predicting factors for the death of CHF patients.The power of RVDD to predict mortality was examined by ROC curves.The area under the curve was 0.805(95％ CI:0.798-0.812,P ＜ 0.01).Conclusion RVDD increases the risk of death in patients with CHF.RVDD is a significant independent predictor for death among patients with CHF.

Objective: To observe the influence of transcutaneous CO2emission (TCE) at points on the meridian or beside the meridian after different stimulations like acupuncture De-qi, sham acupuncture, study the correlation between acupuncture De-qi and local energy metabolism through TCE. Methods: Twenty healthy volunteers (male 8, female 12, average age 29 years old) were selected. Before, during and after five different acupuncture Neignan (PC 6), the TCE was measured at Quze (PC 3), point A [at the lower one fourth of line between Tianquan (PC 2) and Quze (PC 3)], point B [at the middle of line between Ximen (PC 4) and Quze (PC 3)], point C (2 cm ulnar side point A) and point D (2 cm ulnar side point B) with a high sensitive C02 instrument (Frewil-Q.F., made in China). The measure results were compared. Results: The comparison on value of TCE before and after the acupuncture, in Sham acupuncture and shallow acupuncture groups, it increased in all five points; in De-qi acupuncture group, there are significant increase on point A, point B, and Quze (PC 3), it has statistic significance, but there are no significant increase on point C and D. After Ximen (PC 4) or Daling (PC 7) were pressed to block Neiguan (PC 6), the value of TCE on Quze (PC 3), point A and point B were decreased during acupuncture Neiguan (PC 6), and increased after the block was removed, but there was no significant difference. Conclusion: Sham acupuncture has also some effects on body, it can increase energy metabolism of local skin, it may be the reason that shallow acupuncture without qi amving can obtain clinical efficacy. The operation method of traditional qi arriving acupuncture can increase energy metabolism of relevant meridian skin, mechanical press can reduce this effect.

Objective To investigate the expression of arginase Ⅰ(ARG1)in hepatocellular carcinoma(HCC)and to analyze its correlation with clinicopathological features.Methods The expression of ARG1 at protein level in 167 samples of HCC and corresponding adjacent liver tissue was detected with high-throughput tissue microarray technique and immunohistochemistry.The correlation between ARG1 expression and clinicopathological features was analyzed with x2 test and Spearman rank correlation analysis.The expression of ARG1 at mRNA level in 68 samples of HCC and corresponding adjacent liver tissue was determined by real-time polymerase chain reaction(real-time PCR).Results The expression of ARG1 at protein level in HCC(3.540±3.702)was significantly lower than that of the corresponding adjacent liver tissues(10.290 ± 2.303)(t=-22.421,P=0.000).The ARG1 expression was correlated with differentiation degree of HCC,histological grade,vascular invasion,preoperative level of α-fetoprotein(AFP)and recurrence after operation(all P＜0.05).The ARG1 expression at mRNA level in 68 HCC tissue[0.0997(0.213)]was lower than that of the corresponding adjacent liver tissues[0.563(0.459)],and the difference was statistical significant(u=-6.544,P=0.000).Conclusion Low expression of ARG1 in HCC may take part inHCC genesis and development.Detecting the expression of ARG1 may be helpful in HCC diagnosis,differentiation degree and prognosis assessment.

Accurate determination of HIV-1 proviral burden and viral load is very useful in prognosis of HIV-1 infected patients and in assessment of drug for therapy of AIDS patients. In order to establish a quantitative method in detecting HIV-1 proviral burden and viral load, 8E5 cell line and a recombinant RNA constructs were used as the HIV-1 proviral DNA and viral RNA external references, respectively. The PCR products were labeled with the fluorescent DNA dye SYBR green. The amount of burden or load was measured by GeneAmp 5700 Sequence Detection System. Using this method, the HIV-1 proviral burdens in PBMC of patient and in cell suspension treated with the compounds AZT, GL and WT were measured. HIV-1 viral loads in supernatant of the cell culture treated with the above compounds were also determined. The therapeutic indices (TIs) of the compounds calculated based on the inhibition of virus induced syncytial formation, and inhibitionn of proviral burdens and viral loads were compared, and their TIs successively increased. The fluorescent real time quantitative PCR possesses very good specificity, sensitivity and duplication. TI value of a drug based on inhibition of proviral burden in cell culture, and the proviral burden in PBMC of patient may be useful in evaluating a drug on eradicating provirus from resting and memory CD4 T cells.

Objective To determine the activities of 131I for treating differentiated thyroid carcinoma with diffuse pulmonary metastases ( DTC-DPM ) from the perspective of internal radiation dosimetry.Methods According to Medical Internal Radiation Dosimetry (MIRD) schema, the activity constraint,from which the whole bdy retention at 48 h should not exceed 2.96 GBq (2.96 GBq rule), was converted to dose-rate constraint(DRC) to lungs at 48 h ( DRCLU ·48 h ) in 131I therapy for DTC-DPM. Based on the assumption of DRCLU·48 h at 48 h in lung, the fractions of whole body activities ( F48 ), the effective half times of 131I in lungs ( TLL ) and the remainder of body ( TRB ) were 0.6-0.9, 20- 120 h, and 10- 20 h, respectively. The maximum safe activities of 131I for different human phantoms from the Organ Level Internal Dose Assessment (OLINDA) software were calculated. Results According to MIRD schema and 2.96 GBq rule, DRCLU ·48 h should not exceed 46.4 mGy/h in 131I therapy for DTC-DPM. Depending on varying F48 h,TLL and TRB, the maximum safe activities of 131I were 6.77-81.36, 5.29-56.20, 5.08-55.19 and 3.87-40. 52 GBq for the male adult, female adult, 15-year-old, and 10-year-old patients with DTC-DPM, respec tively. Conclusion Dosimetry-guided 131I therapy for DTC-DPM considers adequately the differences of 131I kinetics in individual patients and can adjust administered activities of 131I on the precondition of avoiding radiological pneumonitis and pulmonary fibrosis.
